We're dividing 399701 by 10 
Let's see how many times 10 fits into 399701.

Let's proceed to step 1:
3 divided by 10 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 10

Moving on to step 2:
The number 10 fits into 39 3 times, leaving a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 30 from 39 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 10

Advancing to step 3:
10 goes into 99 9 times with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we subtract 90 from 99, we get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 10

Moving on to step 4:
10 can be fit into 97 9 times, resulting in a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 399.0
Subtract 90 from 97 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 10

Let's proceed to step 5:
If we divide 70 by 10, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 3997.0
If we take 70 away from 70, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 10

Going ahead to step 6:
The number 10 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 39970.0
Subtract 0 from 1 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
The number 10 fits into 10 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 39970.1
The remainder is 0 after subtracting 10 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39970.1
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 39970.1
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 39970.1 with a remainder of 0.0.
